The proposed research addresses the urgent need to reduce suicide rates among teens. This will be the first study that the investigators know of that will examine the feasibility and preliminary effectiveness of augmenting a suicide-focused treatment (Dialectical Behavior Therapy, \[DBT\]) with an evidence-based treatment protocol for insomnia (a digital version of Cognitive Behavioral Therapy for Insomnia \[CBT-I\]). The goal of this clinical trial is to learn providing insomnia treatment in conjunction with suicide-focused treatment leads to greater reductions in suicidality and self-harm than suicide-focused treatment alone. Participants will be randomly assigned to receive 6 months of DBT plus CBT-I or to DBT alone and will complete research assessments measuring suicidal ideation, self-harm behavior and insomnia symptoms every four weeks over the course of the study, as well as one post-treatment follow-up assessment. Participants will also wear a device on their wrist (like a Fitbit or wristwatch) for 10 days following each assessment to collect data about their sleep.
